Vacuum gauge

Two options for a dash mounted vacuum gauge; air filter or fuel filter restriction. Sometimes they're disguised as a differential gauge, but it's still a vacuum gauge at heart. No manifold vacuum on modern diesels, all boost.

I have been wrong before, I'll probably be wrong again.

As a side note:  I suggest y'all look at your owners manual before getting worried about a little air filter restriction.  Most trucks have a restriction indicator on/near the filter housing.  It will tell you when to replace or clean your filter.  On our farm equipment, the manual says when it indicates service is due, wait until the next servicing, which for us was the next morning.  Remember, the more clogged the filter, the better job it does at removing particulate.

Could be a fuel vac gauge. Basically the same as the air gauge. It lets you know when the fuel filter is getting plugged.
